Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks thicken the dressing into a rich, creamy custard when cooked gently.
- Vinegar
- Adds acidity that sharpens the dressing and balances the sweetness and richness.
- Sugar
- Sweetens the dressing, balancing the sharpness of the vinegar and mustard.
- Potatoes
- Form the bulk of the salad, absorbing the dressing and providing its main texture.
- Whipped cream
- Folded in at the end to lighten the dressing and add moisture and a smooth, creamy texture.
The step that matters
Cook the dressing until thick. The egg yolks thicken as they heat, but overheating can scramble them. A double boiler applies gentle heat, so the dressing thickens smoothly without curdling.
Swap the celery
The recipe marks celery as optional. How well each one fits the dish's main ingredients (egg, vinegar, sugar, mustard, potato, onion, cream):
- Garlicfits better
- Capersfits better
- Tarragonfits better
- Celerythe original
Fit is the average pairing score against egg, vinegar, sugar, mustard, potato, onion, cream. Candidates are from the same food group and used in at least 100 recipes.
